Definitions
- the present invention relates to a burner for a gas-cooker with an interchangeable circumferential ring i.e. a burner in which the base ring can be replaced to adapt it to the requirements of the cooking hob on which it is fitted.
- Gas burners for domestic use generally comprise a base element, comprising the gas injector, and the body of the burner, resting on the base element and forming a Venturi to mix the gas with the primary air, together with passages for the mixture up to the openings of the flame exits.
- the primary air can be fed from under the cooking hob or (preferentially in the case of cooking hobs separated from the main body of the economic cooker) from above the cooking hob.
- the burner doesn't require any external element to convey the primary air and therefore the burner can have an essentially cylindrical external configuration with a vertical axis.
- US-A-4 565 523 is representative for the preamble of claim 1 where the cylindrical burner is surrounded by a sheet metal ring, generally curved in shape, which rests freely on the hob, has an ornamental function and can also help to prevent liquid from penetrating into the lower part of the cooker.

Description
- The present invention relates to a burner for a gas-cooker with an interchangeable circumferential ring i.e. a burner in which the base ring can be replaced to adapt it to the requirements of the cooking hob on which it is fitted.
Gas burners for domestic use generally comprise a base element, comprising the gas injector, and the body of the burner, resting on the base element and forming a Venturi to mix the gas with the primary air, together with passages for the mixture up to the openings of the flame exits. - The primary air can be fed from under the cooking hob or (preferentially in the case of cooking hobs separated from the main body of the economic cooker) from above the cooking hob.
- In the first case, the burner doesn't require any external element to convey the primary air and therefore the burner can have an essentially cylindrical external configuration with a vertical axis. US-A-4 565 523 is representative for the preamble of claim 1 where the cylindrical burner is surrounded by a sheet metal ring, generally curved in shape, which rests freely on the hob, has an ornamental function and can also help to prevent liquid from penetrating into the lower part of the cooker. As described, this ring is simply resting on the hob and therefore its axial and radial position with respect to the burner is always very approximate and unstable.
In gas burners which collect the primary air from above the cooking hob, it is, however, necessary to convey the air toward the interior of the burner and an external circumferential ring is therefore provided, pressed as one piece with the body of the burner, which stretches toward the lower part in the direction of the cooking hob and forms with the latter, when the burner is fitted, a circumferential passage which admits the required primary air. This one-piece external ring, while fulfilling its own function effectively, has the disadvantage of constituting an aesthetically anomalous element on the cooking hob, which is generally enameled and colored, as the upper covers of the burners are also enameled and colored. - Based on the above premises, it is now the principal purpose of the present invention to provide a burner with an external ring which can easily be adjusted to the aesthetic requirements of the different cooking hobs.
In the case of burners which collect air from above the cooking hob, the purpose of the invention is to provide a burner with external ring which adjusts to the aesthetic requirements of the different cooking hobs while always maintaining its own exactly defined functional characteristics, with the surface of the cooking hob, and a circumferential passage for the entry of the primary air toward the interior of the burner.
Such purpose is achieved by the features of the characterising portion of claim 1. - Preferably, the said ring circumferential is curved and turned toward the cooking hob, like an annular skirt, and is made of a different material than the body of the burner, in particular, though not exclusively, in enameled steel.
- The burner according to the invention presents numerous advantages compared to the known technique. The skirt fitted to the base of the body allows the essential components of the burner to be produced as a single model and subsequently be modified on the basis of aesthetic requirements or at the request of the fitter of the cooking hob, in terms of shape, color, brightness etc. by applying different circumferential rings without any increase in the general cost of the burner and, in the case of collecting of the air above the cooking hob, maintaining the good operating characteristics of the one-piece burner and ring.
- The invention will now be described in more detail, with reference to the enclosed table of sketches, which are illustrative, but not limiting, and in which:
- Figure 1 is a vertical section of a burner fitted to the cooking hob, of the type which collects the primary air from above the cooking hob,
- Figure 2 is a prospective view of the burner complete with skirt.
- The
skirt 11 can be fitted by means of screws, rivets or any other mechanical means, to the lower part of the body 4 and is shaped as a ring curving toward the cooking hob 2. - The
cylindrical aperture 13 defines a constant section crossed by the primary air, which penetrates, into the said mixing chamber 6 from the surface of the cooking hob 2. - During assembly of the burner, the
skirt 11 is fitted directly onto the under face of the body 4 by means of studs, screws, rivets, as previously mentioned, or also by means of a locking engagement, e.g. bayonet joint, or by screwing it onto a threaded area of the body of the burner. - In the particular case illustrated,
projections 12 are provided, which are extensions from the lower part of the body of the burner 4 and engage in holes prepared in thering 11 and are then riveted to fix the latter. - A generic domestic burner for gas-cookers is shown in the Figures of the type which collects the primary air from above the cooking hob, provided with a single flame crown, but obviously the
skirt 11 can be fitted without distinction to the body of burners with two or more concentric flame crowns. This fitting has the advantage of further subdividing, and to a greater distance from the burner, the secondary air between that destined for the internal crown and that destined for the external flame crown. - The fitting to the body of the burner by mechanical means of an external ring or skirt in a material different from that of the burner, particularly though not exclusively in any enameled steel, allows not only the functional requirements, but also all the aesthetic requirements related to the configuration of this ring - its coloration, brightness and other - to be satisfied, thus giving burners which, while having a unified base and body, can also be adapted easily and at reduced cost to every aesthetic requirement of the consumers.
